• Work collaboratively in the development, optimization, and scale-up of bioconjugation reactions, purification steps, and characterization approaches for conjugate biotherapies.

• Hands-on execution of chromatographic purifications (affinity, hydrophobic interaction, and ion exchange chromatography), membrane filtrations (normal and tangential flow filtrations), buffer and solution preparation, conjugation reaction work-up.

• Perform, develop and optimize bioanalytical characterization (HPLC, UPLC, LC-MS, MALDI, MALS, colorimetric assays, etc.) of bioconjugate products.

• Authoring and review of relevant documentation including laboratory notebooks, process development reports, protocols, batch records, SOPs, technical presentations.
